The α-particle in nuclear matter

0 The α - particle in nuclear matter

Among the light nuclear clusters the α-particle is by far the strongest bound system and therefore expected to play a significant role in the dynamics of nuclei and the phases of nuclear matter. To systematically study the properties of the α-particle we have derived an effective four-body equation of the AltGrassberger-Sandhas (AGS) type that includes the dominant medium effects, i.e. self ene...

Two-particle properties in nuclear matter at finite temperatures

Correlation effects in nuclear matter at finite temperatures are studied for subnuclear densities (ρ < ρ0) and medium excitation energy, where a nonrelativistic potential approach is possible. A quantum statistical approach is given, where clusters are treated under the influence of a clustered medium treated within a mean field approximation. Spectral functions, in-medium cross sections, and r...

Single Particle Spectrum and Binding Energy of Nuclear Matter

In non-relativistic Brueckner calculations of nuclear matter, the self-consistent single particle potential is strongly momentum dependent. To simplify the calculations, a parabolic approximation is often used in the literature. The variation in the binding energy value introduced by the parabolic approximation is quantitatively analyzed in detail. It is found that the approximation can introdu...
